Abstract

A computer implemented method for planning an object which comprises a multitude of single parts and subassemblies, especially an aerospace object, the method comprising: calculating the total weights of the subassemblies and/or of the object on the basis of the data sets of the single parts and the subassemblies, wherein measured weights are used preferably to calculated weights, and calculated weights are used preferably to target weights for the calculation of the total weight(s) of the subassemblies and/or of the object, and calculating and providing the information about the shares of the used weight types in the calculated total weights. The invention further also relates to a manufacturing system and a computer implemented construction module.

1 . A computer implemented method for planning an object which comprises a multitude of single parts and subassemblies, especially an aerospace object,
 wherein a time overlap of the construction phase and the production phase of the object is present,   wherein, in the construction phase, for each single part, for each subassembly and for the object, a data set is created,   wherein the data sets of each single part and each subassembly indicate, as different weight types, a target weight, a calculated weight and a measured weight,   wherein, in the production phase, real single parts and real subassemblies are manufactured and weighed,   the method comprising:   calculating the total weights of the subassemblies and/or of the object on the basis of the data sets of the single parts and the subassemblies,
 wherein measured weights are used preferably to calculated weights, and calculated weights are used preferably to target weights for the calculation of the total weights of the subassemblies and/or of the object, and 
   calculating and providing the information about the shares of the used weight types in the calculated total weights.   
     
     
         2 . The method of  claim 1 , wherein the data set of the object indicates a target weight of the object and wherein information about the ratio of the calculated total weight of the object in relation to the target weight of the object is calculated and provided. 
     
     
         3 . The method of  claim 1 , wherein
 information about the ratio of a number of single parts and subassemblies, whose measured or calculated weights are present, in relation to the total number of single parts and subassemblies and/or   information about the ratio of a number of single parts and subassemblies, whose measured weights are present, in relation to the total number of single parts and subassemblies and/or   information about the ratio of the number of single parts and subassemblies, whose measured weights or calculated weights are present, in relation to the number of the single parts and subassemblies whose measured weights are present   is calculated and provided.

         6 . The method of  claim 1 , wherein, at the calculation step of the total weights of the subassemblies and/or of the object, the weight of subassemblies grouping single parts is used instead of the weights of the respective single parts. 
     
     
         7 . The method of  claim 1 , wherein, at the calculation step of the total weight of the subassemblies and/or of the object, weight changes due to the assembly of single parts being taken into account.

   a means for total weight determination which is configured for calculating the total weights of the subassemblies and/or of the object on the basis of the data sets of the single parts and the subassemblies,
 wherein the means for total weight determination uses measured weights preferably to calculated weights, and calculated weights preferably to target weights for the calculation of the total weights of the subassemblies and/or of the object, and wherein 
   the means for total weight determination is configured for calculating and providing information about the shares of the used weight types in the calculated total weights.

         10 . The module of  claim 8 , with links to one or more construction systems for a 3D representation and/or with links to one or more production data management systems, whose data may be integrated into the data sets. 
     
     
         11 . The module of  claim 8 , including another module allowing for storing the interrelations of parameters during any first use of a data set, such that the interrelations of parameters are assessable in terms of a search matrix when creating further data sets. 
     
     
         12 . The module of  claim 8 , including another module which is configured for the output of data from the data sets of the single parts, subassemblies or from the object in the form of a short description with relevant data for any person involved in the generation or evaluation of the data sets. 
     
     
         13 . The module of  claim 8 , comprising another module configured for automatically informing any person involved in the generation or evaluation of the data sets at each change of content of the data sets via a communication system for an intranet and/or the internet.
